The invention provides a power supply circuit, a motor controller and a vehicle, the power supply circuit comprises an anti-reverse connection circuit and a wake-up circuit, the anti-reverse connection circuit comprises a first switch tube and a second switch tube, and the first switch tube and the second switch tube are connected in series between a low-voltage power supply and a post-stage circuit and are oppositely arranged; and when the wake-up circuit receives at least one of a power-on wake-up signal, a network wake-up signal and a post-stage power supply signal, the first switch tube and the second switch tube are controlled to be switched on, so that the low-voltage power supply supplies power to the post-stage circuit. And when the wake-up circuit does not receive the power-on wake-up signal, the network wake-up signal and the post-stage power supply signal, the first switch tube and the second switch tube are controlled to be disconnected, so that the low-voltage power supply is disconnected from the post-stage circuit, and rapid power-off of the post-stage circuit is realized. The on-off of the first switch tube and the second switch tube is controlled by the wake-up circuit according to the power-on wake-up signal, the network wake-up signal and the post-stage power supply signal, so that the power-on and power-off of the post-stage circuit are controllable, and the reliability of the power supply circuit is improved.

    本申请提出一种供电电路、电机控制器及车辆,其中,供电电路包括防反接电路和唤醒电路,防反接电路包括第一开关管和第二开关管,第一开关管和第二开关管串联于低压电源和后级电路之间并相反设置,唤醒电路在接收到上电唤醒信号、网络唤醒信号和后级电源信号中的至少一者时,控制第一开关管和第二开关管导通,以使低压电源为后级电路供电。而当唤醒电路未接收到上电唤醒信号、网络唤醒信号和后级电源信号时,则控制第一开关管和第二开关管断开,以将低压电源与后级电路断开,实现后级电路的快速下电。第一开关管和第二开关管由唤醒电路根据上电唤醒信号、网络唤醒信号和后级电源信号控制通断,使得后级电路的上下电可控,提高供电电路的可靠性。
